This sound seemed to be a signal, and a series of 'clicks' and cracks continued to sound.

The overhead tiles fell more sharply, falling to the ground, some of them smashing against the edge of the pool covered with unknown plants, making a loud noise.

The laboratory had been abandoned for many years, infested by mutated plants, and was already crumbling, and the slightest movement at this time could cause extremely bad consequences.

The cracks in the roof cracked wider, and the ceiling overhead squeaked, creaked, creaked.

This scene is clearly the posture of the laboratory about to collapse.

Song Qing cursed carefully, this laboratory will not collapse sooner or later, and there will be problems as soon as the two of them come in at this time, and it is really too lucky.

The roof of the house, which was already split and cracked overhead, began to collapse, and a large number of stone bricks fell down, in order to avoid being injured by the collapsed building, Song Qingxiao had to retreat inside.

The huge pillar on the side of the laboratory made an overwhelmed sound, and Song Qingxiao turned his head and looked at the pillar that made the sound.

At a glance, Song Qingxiao noticed the strangeness of the pillar.

The column was originally extremely thick, supporting the façade of the Changsheng Science and Technology Hall, but for some reason, something seemed to have scratched the middle of the column, leaving indelible traces.

The cement for irrigation outside was stripped away, revealing strips of steel bars that had been bent and deformed inside.

There was a palm-sized thing hanging on the cement below, like a piece of skin, Song Qingxiao was about to reach out to fish, the pillar began to crack from the middle with a 'bang', and the support column bent as soon as the rest of the place fell.

The stone bricks 'crackled' down, the sound of glass shattering, and the 'boom' of collapse overpowered the thunder.

A large amount of dust was splashed around, sand and stones flew around, the collapsed ceiling blocked the only light, and the entrance and exit of the laboratory were suddenly sealed by a large amount of stone bricks and other construction waste, forming a triangle-like sealed space.

The room was pitch black, Song Qingxiao pinched her nostrils and quickly retreated, until she stuck to a wall in the laboratory, and then stood firm.

The sound of bricks sliding outside the laboratory slowed down for a while, and the trembling of the ground had subsided, and the sound of some fine tiles sliding was almost negligible.

With such a big movement, if there were any dangerous creatures in the laboratory, I am afraid that they would have been awakened a long time ago.

Song Qingxiao and No. 7 held their breath in unison, listening to the sounds around them.

It was extremely quiet, and through the uncollapsed ceiling on half of the laboratory, you could hear the lightning and thunder outside.

The sealed indoor air did not smell good, and a large amount of dust mixed with a strange smell poured into the noses of the two, and the two were quiet for a while, and the somewhat dry voice of the seventh sounded:

"Isn't it, guess, guess wrong?"

Her voice was a little suppressed in the cramped space, with a hint of unceasing joy and a well-hidden malice.

From the place where the sound came from, Song Qingxiao judged that No. 7 was about four or five meters away from him.

Song Qingxiao also hoped that his judgment of the dangerous mutated creatures on the island had gone wrong, and of course he didn't want something difficult to deal with here.

But the vanishing mutant creatures on half of the island, the deformed e-iron fences, the shattered glass, and the deformed pillar she saw before the lab collapsed all showed that there was once something terrible here.

She still thought of the piece of soft leather that she had seen hanging on the deformed pillar before the laboratory collapsed, but unfortunately at this time, as the laboratory fell, the thing was probably buried in the stone pile.

"Maybe."

She replied, backhand touching the wall against which her back was leaning.

Before this place collapsed, she roughly swept the inside, and it was a hall of nearly 100 square meters.

Some of the equipment and materials in the hall were moved away as early as the beginning of Zhou's evacuation of the island, but whether it is from the perspective of floor area or environment, this place does not look like the base camp of Zhou's Changsheng Technology, it should just be the façade of a research institute.

A real research center should be hidden somewhere else.

The way out ahead has been blocked by waste rocks, and if you want to move away the abandoned stones and other heavy objects, it is not something that can be done with a pair of hands for the time being, and I don't know that the Zhou family has not arranged other ways out at the beginning of the establishment of Changsheng Technology.

The wall where her palm was attached was cold and smooth, like polished marble, and Song Qingxiao followed the stone to find some clues.

At the sound of 'Sissisoso', Seven was probably in line with her idea, and she was also groping for her surroundings.

There was a sudden 'click' sound in the sealed space, as if someone had touched the fallen garbage or the tiles had been crushed.

But Song Qingxiao's mind was already tense to the extreme at this time, and when he heard the sound, he instinctively leaned his back against the wall, holding the dagger, even if he couldn't see the surrounding environment clearly, he turned his head to be vigilant.

"Who?"

Number Seven seemed to be a cat whose tail had been stepped on, and asked abruptly.

Her reaction proved that the previous movement had nothing to do with her, either the stone bricks and other objects that had slipped down made a noise when they moved, or something was hiding in the dark, eyeing people and preparing to hurt people.

It could be a mutated creature or a human being, still nowhere to be seen, carrying the silver box of Three.

After the seventh sounded, he had already noticed that something was wrong, and the next second Song Qingxiao heard a strong wind blowing, followed by a strange sound of 'ding', like the sound of a metal object piercing into a stone.

At the same time, there was a hurried footstep, a screeching sound from a fingernail clutching the floor, which was supposed to be the movement of Seven.

In the space where you can't see your fingers, sure enough, someone appeared!

As soon as No. 7 spoke, he was locked in the direction, and the anger in his heart can be imagined.

"Song Qingxiao, is that you?"

She dodged twice in succession, with a somewhat eerie tone and a bit of murderous intent.

In response to her, there was silence, and the reason why No. 7 threw out the problem at this time, Song Qingxiao could guess it without thinking about it, it was nothing more than trying to cause trouble.

Everyone knew that the moment the laboratory collapsed, the stealthy No. 3 also mixed in, waiting for an opportunity to hurt people.

Darkness became her best protective color, and as soon as she appeared, she began to sneak up on people, and even if Seven was on guard, she should have been caught off guard.

At this time, she may not have known that it was No. 3 who attacked her, she deliberately spoke, trying to lead Song Qingxiao to make sure she was located.

Among the three, No. 7 and No. 3 were already injured, only Song Qingxiao's appearance was intact, and if possible, No. 3 would definitely be willing to sneak up on her, make her hang the lottery, and exclude her from the three trialists.

The sneak attack on No. 7 is just a next move, and No. 7 is like a mirror in his heart.

As soon as her voice fell, she didn't get a response from Song Qingxiao, and what was waiting for her was a sneak attack like a storm on the third day.
